Changing Spindle Speed - Grizzly T32006 Owner's Manual

Changing
Spindle Speed
The Model T32006 has a variable-speed
spindle that operates up to 5000 RPM.
This speed range is achieved using the
variable-speed dial and the pulley system
it controls.
Once you know the recommeded spindle
speed for your project (see Choosing
Spindle Speeds on Page 18), adjust the
drive belt to the slowest speed range that
provides the speed you need. This will
allow for more control and extend your
machine life.
